[0144] High-level configuration; functions of random access resources; purpose of the first communication node initiating random access, measurement results of the first communication node, measurement results of the second communication node, type of the first communication node, capabilities of the first communication node, one or more thresholds, priority of frequency resources, priority of random access resources, frequency range of frequency resources, bandwidth, and predefined parameters.
[0145] At least one of the target frequency resources and the target random access resources can be indicated by the base station, predefined, or selected by the terminal.
[0146] One or more thresholds can be used to measure the quality of the measurement results.
[0147] In this embodiment, at least one of the target random access resource configuration information, target frequency resource, and target random access resource can be determined based on higher-layer configuration. The higher-layer configuration includes random access resource configuration and / or frequency resource configuration. For example, when a terminal receives configuration information, if the configuration information includes a frequency resource associated with a second type of random access resource, the terminal can select the frequency resource associated with the second type of random access resource and initiate a random access procedure using the second type of random access resource; otherwise, the terminal selects a first type of random access resource to initiate a random access procedure.
[0148] In this embodiment, at least one of the target random access resource configuration information, target frequency resources, and target random access resources can be determined based on the function of the random access resource and / or the purpose of the terminal initiating random access. For example, a first type of random access resource is used for the configuration request of the random access resource configuration information, and a second type of random access resource is used for the terminal to initiate initial access; when the purpose of the terminal initiating random access is to initiate initial access, the terminal selects the second type of random access resource to initiate the initial access procedure; if the terminal has not obtained the second type of random access resource configuration information, it uses the first type of random access resource to initiate the configuration request of the second type of random access resource configuration information.
[0149] In this embodiment, at least one of the target random access resource configuration information, target frequency resource, and target random access resource is determined based on the terminal capability. For example, a terminal supporting terminal capability 1 can only initiate a random access procedure using the first type of random access resource; a terminal supporting terminal capability 1 needs to select the frequency resource associated with the first type of random access resource; a terminal supporting terminal capability 2 can initiate a random access procedure using the second type of random access resource; a terminal supporting terminal capability 2 can select the frequency resource corresponding to the second type of random access resource.
[0150] In this embodiment, at least one of the target random access resource configuration information, target frequency resource, and target random access resource can be determined based on the terminal measurement results. For example, each frequency resource has a corresponding reference signal, and the terminal can measure the channel conditions on the frequency resource based on the measurement results of the reference signal; for example, the terminal measures all measurable frequency resources (such as accessible frequency resources), selects the frequency resource with the best measurement results as the target frequency resource based on the measurement results, selects the random access resource associated with the target frequency resource as the random access resource, and initiates the random access procedure.
[0151] In this embodiment, at least one of the target random access resource configuration information, target frequency resources, and target random access resources is determined based on the priority of the frequency resources or random access resources. Each frequency resource corresponds to a priority; the terminal obtains the priority of the frequency resources and selects the frequency resource with the higher priority for access. Similarly, each random access resource is associated with a priority; the terminal obtains the priority of the random access resources and initiates the random access procedure by selecting the random access resource with the higher priority.

[0188] The second communication node may receive an activation request for the configuration information of the second type of random access resource on the first type of random access resource. After confirming the activation request, the second communication node begins detecting random access requests on the second type of random access resource. Alternatively, the second communication node may receive an activation signaling message for the configuration information of the second type of random access resource on the first type of random access resource.

[0197] In this embodiment, the base station can transmit the first type of random access resource configuration information via broadcast. The terminal first receives the first type of random access resource configuration information, and then requests the second type of random access resource configuration information from the base station.

[0198] In one embodiment, transmitting the second type of random access resource configuration information via on-demand transmission includes at least one of the following:
[0199] Based on the request sent by the first communication node, transmit candidate random access resource configuration information to the first communication node;

The target random access resource configuration information is random access resource configuration information associated with the target frequency resource. The target random access resource configuration information can be specified or selected by the base station.
[0205] The following describes a random access resource acquisition method through different embodiments.
[0206] Method 1: The terminal directly receives multiple random access resource configuration information, that is, both the first type of random access resource configuration and the second type of random access resource configuration are transmitted to the terminal by the base station in the form of broadcast.
[0207] Example 1
[0208] The terminal receives random access resource configuration information in cell 1. This configuration information is used to provide configuration related to random access resources. The random access resource configuration information is transmitted in a broadcast manner. The random access resources include one or more first-type random access resources and one or more second-type random access resources. Each random access resource corresponds to a frequency resource, such as a virtual carrier, cell, carrier, component, bandwidth, etc.
[0209] The terminal selects a target random access resource and initiates a random access procedure on the target random access resource.
[0210] Method 2: The terminal first receives the first type of random access resource configuration information, and then requests the second type of random access resource configuration information. The first type of random access resource configuration information is transmitted to the terminal by the base station via broadcast, while the second type of random access resource configuration information is transmitted to the terminal by the base station via on-demand transmission.
[0211] Method 2.1: The terminal requests random access resource configuration information, the base station transmits all candidate random access resource configuration information, the terminal receives all candidate random access resource configuration information, and selects the target random access resource configuration information from them.
[0212] Example 2
[0213] The terminal receives the first type of random access resource configuration information in cell 1. The first type of random access resource configuration information is transmitted to the terminal by the base station in the form of broadcast.
[0214] The terminal selects a first type of random access resource and transmits a configuration request for second type of random access resource configuration information on that first type of random access resource. The configuration request for second type of random access resource configuration information is used to request the base station to transmit the second type of random access resource configuration information. Optionally, each random access resource (including the first type of random access resource and / or the second type of random access resource) corresponds to a frequency resource, such as a virtual carrier, cell, carrier, component, bandwidth portion, etc.
[0215] The base station transmits the random access resource configuration information corresponding to the candidate frequency domain resources, i.e., the candidate random access resource configuration information, according to the terminal's request; the terminal receives the candidate random access resource configuration information. The candidate frequency domain resources include at least one of the following: frequency resources related to the frequency resources corresponding to the first type of random access resources, frequency resources of the same cell, frequency resources of the same cell group, frequency resources of the same area, components of the same cell, and bandwidth portions of the same cell.
[0216] Optionally, the candidate frequency resource is a frequency resource related to the frequency resource corresponding to the first type of random access resource. For example, the potential frequency resource has the same coverage area as the frequency resource corresponding to the first type of random access resource; the coverage area of the potential frequency resource is a subset of the coverage area of the frequency resource corresponding to the first type of random access resource; the potential frequency resource and the frequency resource corresponding to the first type of random access resource have an association relationship, which is indicated by the base station or configured by higher layers.
[0217] Optionally, the potential frequency resources are frequency resources within the same area / cell group / cell / virtual cell / carrier / virtual carrier. Optionally, the potential frequency resources and the frequency resources corresponding to the first type of random access resources belong to the same cell / virtual cell / carrier / virtual carrier.
[0218] For example, the first type of random access resource is a random access resource broadcast on cell 1. Cell 1 contains or is associated with N components (these components can be cells, carriers, frequency bands, bandwidth portions, resource blocks, etc.). One type of second random access resource configuration information corresponds to one component of cell 1; the terminal uses the first type of random access resource to transmit a configuration request for the second type of random access resource configuration information; the base station responds to the configuration request and transmits N types of second type random access resource configuration information corresponding to the aforementioned N components.
[0219] Each candidate random access resource configuration information corresponds to a candidate random access resource.
[0220] The terminal selects a target random access resource from the candidate random access resources, and initiates a random access procedure on the target random access resource.
[0221] Method 2.2: The terminal first selects the target frequency resource, then requests the random access resource configuration information corresponding to the target frequency resource, and the terminal receives the target random access resource configuration information.
[0222] Example 3
[0223] The terminal receives the first type of random access resource configuration information in cell 1. The first type of random access resource configuration information is transmitted to the terminal by the base station in the form of broadcast.
[0224] The terminal selects a target frequency resource. Optionally, each frequency resource is associated with a random access resource configuration (including a first type of random access resource and / or a second type of random access resource). The frequency resource includes virtual carriers, cells, carriers, components, bandwidth portions, etc.
[0225] The terminal transmits a configuration request for second-type random access resource configuration information based on the first-type random access resource configuration information. Optionally, the terminal transmits a configuration request for second-type random access resource configuration information corresponding to the target frequency resource based on the first-type random access resource configuration information, i.e., a configuration request for the target random access resource configuration information. For example, the terminal transmits a configuration request for second-type random access resource configuration information on the first-type random access resource; if the random access resource configuration information corresponding to the target frequency resource selected by the terminal has not been acquired by the base station or broadcast by the base station, then the terminal transmits a configuration request for the random access resource configuration information corresponding to the target frequency resource.
[0226] Optionally, the configuration request for the second type of random access resource configuration information requested by the terminal is associated with a target frequency resource. For example, the generation of the configuration request signal or channel for the second type of random access resource configuration information is related to the target frequency resource identifier; the configuration request signal or channel for the second type of random access resource configuration information carries the target frequency resource identifier; and the configuration request for the second type of random access resource configuration information is transmitted on the first type of random access resource associated with the target frequency resource.
[0227] The base station responds to the configuration request for the second type of random access resource configuration information and transmits the second type of random access resource configuration information.
[0228] The terminal receives the second type of random access resource configuration information, which is the configuration information of the random access resource corresponding to the target frequency resource. That is, the terminal receives the target random access resource configuration information; the terminal initiates a random access procedure on the second type of random access resource.
[0229] Method 2.3: The terminal requests random access resource configuration information, the base station allocates target random access resource configuration information to the terminal; the terminal receives the target random access resource configuration information.
[0230] Example 4
[0231] The terminal receives the first type of random access resource configuration information in cell 1. The first type of random access resource configuration information is transmitted to the terminal by the base station in the form of broadcast.
[0232] The terminal transmits a configuration request for the second type of random access resource configuration information on the first type of random access resource. The configuration request for the second type of random access resource configuration information is used to request the base station to transmit the configuration information of the second type of random access resource. Optionally, each random access resource (including the first type of random access resource and / or the second type of random access resource) corresponds to a frequency resource, such as a virtual carrier, cell, carrier, component, bandwidth, etc.
[0233] The base station responds to the second type of random access resource configuration request and transmits target random access resource configuration information. This target random access resource configuration information is the random access resource configuration information corresponding to the target frequency resource. Optionally, the target random access resource configuration information is specified or allocated by the base station.
[0234] The terminal receives the target random access resource configuration information, which may be the second type of random access resource configuration information; the terminal initiates a random access procedure on the target random access resource.
